Application 3 Claims.

My invention relates to a novel window construction and has for its vobject the provision of a Window which has greater adjustability than any window heretofore devised.

A further object of my invention is the provision of a novel window construction which is economical to manufacture, rigid and extremely durable.

A still further object of my invention is the provision of a window construction wherein the window'sash may be either vertically adjusted in its frame, or opened pivotally with respect thereto.

A still further `object of my invention is the provision of a pair of vertically arranged, laterally offset window sashes each of which is so mounted in a common frame structure that it may be either vertically or pivotally opened and closed.

A still further object of my invention is thev provision of a novel friction braking means for holding the sash in a manually set pivotal position.

A still further object of my invention is the provision of such'a windowconstruction having means for positively locking Athe sash against raising or lowering, and pivotal movements from `a normal closed position.

The `above and still further objects of my invention will'become apparent from the following detailed speciiication and attached drawings.

September 5, 1945, Serial No. 614:,47'1Y Referring more particularly to the drawings, the numeral I indicates a window frame in its entirety, preferably and as shown rectangularin shape, having a facing 2, and which is composed of vertical-parallel side members 3 and 4, a header 5 and a sill 6. Projecting outwardlyV from the opposed inner faces of`A the vertical frame members 3 and'll are elongated stop strips l sill 6 to approximately half the height of the side members 3 and 4 of frame I. l

Similar stop strips -lproject outwardly 4from the opposediaLces of side members 3 and 4 but extend downwardly from the header 5 only to approximately half the length of said side members 3y and 4. Stop strips 'l and 8 are in parallel vertical planes which are laterally spacedffor. a purpose which will hereinafter become apparent.

Shown as being secured to the opposed inner faces of vertical frame members 3 and 4 are twopairs of clutch housings or brackets 9, one pair being positioned just above the sill 6 and the `other at approximately the linear centers of members 3 and 4 but laterally outwardly offsetY from the lower pair. Each of said brack-` ets is identical and as shown,.comprises aface platek I0 adapted to be countersunk intothe opposed faces of members 3 and 4 and'hav'ing openings II through which screws or the like IZ are adapted to pass to hold the same securely in position. Faceplates I0 also have enlarged central openings I3. Projecting inwardly from the sides of eachface platel I0 are integrally formed flanges I4.A As shown, anges I4 extend throughrectangular openings l5 in members '3,

and 4 and project outwardly therefrom.

Positioned centrally between flanges III are trunnionflike pivot pins I6 which have squared central portions I1 and threaded inwardly projecting end portions I8. V-Threaded end portions I8 as well as the inner ends of squared central portions I1 project through the enlarged central openings I3 in the face plate -I0 andare adapted to rotate therein. l

Arms I9 are shown as having screw-threaded engagement with inner ends I8 of pivot pin I6.- In fact, arms I9 are drawn up tightly against the outer ends of squared central portions I1, through interposed washers 20, so as to cause pivot pin I6 to rotate therewith. Pivot pins I6 are provided with reduced screw-threaded outwardlyprojecting ends 2I.

- My novel friction braking or clutch-'mechansm will now be described:y .A plurality.' shown as being approximately five in number, of square 1 which extend upwardly from the bre washers 22 which are approximately of the same width as the space between outwardly projecting ilanges I4 of bracket or housing 3, are positioned on the square shanks l1 of pivot pins I6. Fibre washers 22 are shown as having round central openings 23 of a size to allow the square shank I1 to rotate freely therein. Interposed between each of the fibre washers 22 are a like number of round metal washers 24 having squared central openings 25 of a size to assure rotation thereof with the squared shanks I1 of pivot pins I6. 'I'he outwardly projecting reduced ends 2I of pivot pins I6 are equipped with screw-threaded tensioning nuts 23 and enlarged washers or the like 21. Interposed between the washers 21 and the friction washers 22 or 24, whichever the case may be, are coil springs 28. Longitudinally spaced along the arms I3 are a plurality of openings 29.

Shown as being mounted in frame I are matched upper and lower window sashes 30 and 3|, respectively, which are, preferably and as shown, rectangular in shape, and have parallel side members 32, upper cross members 33, and lower cross members 34. Each sash is provided with a conventional glass pane 35. Each of the outer edges of side members 32 is provided with an elongated slot 36 which is adapted to receive flcr sliding engagement therein, one of the arms Lower window 3| when in a normally closed position abuts against the stop strips 1 which limit its movement in an outward direction. Its downward movement is also limited by the sill 6. However, lower window SI is capable of the compound vertical adjustments illustrated in Fig. 1, and the pivotal adjustments or movements illustrated in Fig. 2. To retain the window in any given vertical sliding position (upward from the sill lI5), I provide a conventional plunger pin 38, shown in detail in Fig. 5, and which comprises an open ended tubular housing 31 countersunk into the side members 32 in a horizontal position at the bottom of channels 36. A plunger pin 38 works axially through said housing 31 and has its inner end 39 projecting through an opening 40 in the housing and also through an opening 4I in the side members 32 of the sash as a handle. The outer end of plunger pin 33 projects outwardly through the open end of housing 31 and is under constant tension to move outwardly by virtue of a coil spring 42 interposed between the inner closed end 43 of housing 31 and a stop ange 44 spaced rearwardly from the reduced outer end 45 thereof. The inner reduced end 45 is adapted to iit into the longitudinally spaced openings 29 in the arms I9.

Obviously, when it is desired to move lower sash 3I vertically from one position to the other, the operator pulls outwardly on the handle 39 of the plunger pin 38 so as to remove the inner end 45 from the openings 29 of the arm I9. The window may then be moved to the desired vertical position where plunger pin 33 under tension of spring 42 will move into another opening 29 and thus lock sash 3| against further accidental vertical movement.

The degree of braking or clutching action, which is desired to be applied to the pivotal movements of the lower window SI, may be arrived at by varying the adjustment of tensioning nuts 26 which vary the degree of friction applied between the rotary metallic washers 24 and the non-rotary bre washers 22.

When the top window 30 is in a normally closed position it abuts against stop strips 8 which limit its outward movements as before indicated. Stop strips 8 are sufficiently laterally oset with respect to stop strips 1 so as to allow independent vertical adjustments of both upper sash 3U and lower sash 3l in side by side relationship. When both upper sash 30 and lower sash 3| are in their normally closed position the upper cross member 33 of lower sash 3|, and the lower cross member 311 of upper sash 30 are in substantially the same horizontal plane and may be locked together by a conventional rotary cam locking device which consists of a rotary cam member 4B on the cross member 33 of lower sash 3| and a xed lock flange 41, formed to provide a downwardly opening lock cam receiving channel 48, on the upper edge of member 33 of lower sash 3|. However, when locking members 46 and 41 are disengaged the upper sash 3i! must rely upon the engagement of plunger pin 38 with the openings 29 of the arms I 9 to lock it in the desired vertical position.

inasmuch as the clutch mechanism, associated with the upper arms I9, is identical with that connected to the lower arms I9, it is obvious that the frictional action applied to the parallel movements may be varied in the precise manner as above described.

The benets of my novel invention, above described, are obvious and numerous. To mention but a few, it greatly facilitates the washing of both sides of the window from the inside; makes it possible to direct incoming Ventilating air currents to any desired position in the room; and it makes possible even the total removal of both upper and lower sash for the purpose of removing the storm sash or screens.

While I have described a commercial form of my invention it should be obvious that the same is subject to slight changes and modifications without departing from the spirit of the invention, as defined in the appended claims,

What I 'claim is:

l. A window construction comprising a window frame having parallel sides, and upper and lower sash disposed in the frame in laterally offset parallel planes permitting the sash to be raised and lowered independently, upper and lower stop anges on the frame respectively overlapping opposite outer edge portions of the upper and lower sash and which are co-extensive with their respectively engaged sash, a longitudinally extended outwardly opening channel in the opposite edge of each sash, an arm slidable in each sash channel, one end of each arm being pivotaly anv chored to the frame closely adjacent a horizontal plane intersecting the lower edge of its respective sash when the said sash is in a normal closed position in the frame, whereby either sash may be raised or lowered in a vertical plane independently of the other or may be moved pivotally inwardly independently of the other.

2. The structure defined in claim 1 in further combination with friction means for maintaining the sash against accidental displacement from diiierent pivotally adjusted positions.

3. The structure dened in claim 1 in further combination with friction means for maintaining the sash against accidental displacement from different pivotally adjusted positions, and means for positively locking the sash against raising or lowering, and pivotal movements from a normal closed position.
